Product Description:

Centrifugal Water Pump for Agriculture Application

1.Structure of Centrifugal Water Pump Description

Centrifugal Water Pump is used for transporting pure water or liquids with physical and chemical properties similar to pure water, and the maximum of the medium temperature is 80°C.(type ISR pump reaches 120°C). Widely applied towater supply industry, urban water supply and drainage, metallurgy, power stations, textile, chemical industry, printing and dyeing, ceramics, rubber, heating, waste heat utilization, air conditioning, agricultural irrigation and etc.

2.Main Features of the Centrifugal Water Pump

Q:Attention should be paid to the use of pumps?

7 water pump and pipe interface must be sealed, because if there is debris access, then the pump will cause damage to the interior. 8 for the water pump bearing is also the focus of inspection, use up to check whether the bearings wear,

Q:What is cavitation, centrifugal pump cavitation phenomenon how to solve?

First, what is cavitation?:When the centrifugal pump shell has air, it produces less centrifugal force because the density of the air is much smaller than the density of the liquid. Thus, suction pressure at the entrance to the top of the tank liquid level and pump is bad enough to the liquid storage tank into the pump, the centrifugal pump self suction capability, the centrifugal pump can not transport liquid, this phenomenon is called "cavitation".When a liquid drops at a certain temperature to the vapor pressure at that temperature, the liquid produces a bubble. The phenomenon of producing bubbles is called cavitation. When the cavitation bubbles, flow to the high pressure, the volume of reduced, so as to burst. This due to the pressure of rising bubbles disappear in the liquid in the phenomenon called cavitation bubble collapse.

Q:Must the water pump in the tank be all soaked in water?

Of course, if the motor is overheated, it will burn, and the temperature of the water will drop down.

Q:What are the reasons for sealing damage of centrifugal pumps?

Three, water shortages caused by running dry grinding damage.This phenomenon is more common in mounted form inlet pressure, inlet air, air cavity pump, pump boot, high temperature operation of the mechanical seal friction at high speed, can not be cooled, check the mechanical seal, the spring tension is normal, the friction surface of charred black, rubber hard cracking.Treatment methods: exhaust the pipe and pump cavity air, replace the machine seal.Four, install too tight, observe the mechanical seal of dynamic and static ring plane, if there is serious burning phenomenon, flat black and deep traces, sealing rubber hardens, lose elasticity.This phenomenon is due to tight installation.Treatment methods: adjust the installation height, impeller installed, with a screwdriver to move the spring, the spring has a strong tension, release after the reset, there is 2-4mm moving distance can.

Q:Why is the submersible pump tripped on an electrical switch?

There should be the following reasons: 1) the setting value of the trip switch is too small, and the operating current of the submersible pump exceeds its setting value, and the switch is tripped

Q:What is double hydraulic pump?

Two hydraulic pumps installed on one shaft can be connected to increase output flow, and can also be connected to increase output pressure. See how the demand is. The system can change the mode of application at any time.

Q:What's the pump? Where can I use it?

Working principleIt transfers mechanical energy or other external energy of the prime mover to the liquid, increasing the energy of the liquid. Before the pump starts, the pump shell is filled with the liquid to be transported; after starting, the impeller is driven by the shaft to rotate at high speed, and the liquid between the blades must also rotate. Under the influence of centrifugal force, the liquid is thrown from the center of the impeller to the outer edge and obtains energy, and leaves the outer edge of the impeller at high speed to enter the volute pump shell. In the spiral case, the liquid slows down due to the gradual enlargement of the flow passage, and the part of kinetic energy is converted to static pressure, and finally flows into the exhaust pipe at higher pressure and is sent to the required place. When the liquid flows from the center of the impeller to the outer edge, a vacuum is formed at the center of the impeller. As the pressure at the upper level of the tank is greater than the pressure at the pump inlet, the liquid is continuously pressed into the impeller. Visible, as long as the impeller continues to rotate, the liquid will continue to be inhaled and discharged.

Q:What does "dual purpose" of water pump mean? Please expert advice

2, the pump must pay attention to maintenance after use, for example, when the pump is used up, the water pump should be put clean, it is best to remove the water pipe, and then rinse with water.5, the water pump on the tape should be removed, and then rinse with water after drying in the light place, do not put the tape in the dark damp place. Water pump tape must not be stained with oil, not to tape coated with some sticky things.6, to carefully check whether there are cracks in the impeller, the impeller fixed to the bearing on whether there is loose, cracks and loose if the phenomenon to be timely maintenance, if the water pump impeller should also be above the earth clean.

Q:The distance from the pump button to the ground

After confirming that the fire pump has started running, issue a command signal to the hydrant button to light the green answer light.

Q:What is the difference between centrifugal pump and self suction pump? Which is better?

Centrifugal pumps are vertical, horizontal, single-stage, multi-stage, single suction, double suction, self suction and other forms. The centrifugal pump drives the water to rotate through the high speed rotating impeller blade, and the water is thrown out so as to achieve the purpose of pumping water. The impeller rotates at high speed, forcing the liquid at the center of the impeller to be removed at high speeds, resulting in a low pressure at the center of the impeller, and the liquid in the lower trough is continuously sucked.
